WotLK bestiary presents the Jormungar

The official WoTLK bestiary has been updated yet again with another of the creatures we'll be meeting in Northrend. This time, we're introduced to the Jormungar, a race of massive worms with sharp teeth capable of boring through solid rock. Apparently, they were used by the Nerubians as slave labor to hew out their massive subterranean empire. However, when that empire fell to the Scourge, the Jormungar broke free, and now run rampant, drilling through the permafrost and destroying everything in their path.

It seems likely that the worms themselves are named after the Norse mythological figure Jormungandr, a child of the trickster god Loki, also known as the the World Serpent who surrounds the Earth. In the end times of Ragnarok, he will kill Thor (although Thor will kill him first). Now really, you know that anything bad enough to kill Thor himself is something you have to take notice of, so if these Jormungar are even half as strong as their namesake, it looks like we could have a lot of trouble with them. Maybe we should look to the old massive sandworm Ouro (whose name is likely a homage to another mythical serpent, the Ouroboros), to give us some idea of what we might be facing.
